Identifying the Number of Solutions of a System of Equati
Consider this system of equations:
y = x2
y = x + k
For which value of k does the system have no real number solutions?
For which value of k does the system have one real number solution?
For which value of k does the system have two real number solutions?

stop cheating

step-by-step explanation:

your answer would be 12

x = 3 ± √(5+y)

1. 180°. the sum of the interior angles of a triangle is 180°, for the equilateral triangle that it has three equals side is 60°+60°+60°=180°.

2. 60°. each interior angle of a equilateral triangle is 60°

3. 120°. the measure of ∠m is 120°, the sum of the angles ∠m and ∠n is equal to 180°. so, in order to find the measure of ∠m, we have ∠m+∠n=180° > ∠m=180°-∠n > ∠m=180°-60°=120°.

4. 360°. the sum of the exterior angles of an equilateral triangle is ∠m+∠r+∠x=120°+120°+120°=360°. the exterior angles of any triangle always add 360°.
